Special Issue Information

Dear Colleagues,

Abdominal surgery remains a cornerstone of general and specialized surgical care, encompassing a wide range of pathologies managed through elective and emergency procedures. In recent decades, the field has witnessed the steady integration of minimally invasive and robotic-assisted techniques, which have enhanced patient outcomes in terms of safety, recovery, and complication rates. Despite this progress, challenges remain in optimizing surgical decision-making, managing complex clinical cases, and standardizing care across diverse healthcare systems.

This Special Issue, entitled “Abdominal Surgery: Innovative Techniques and Challenges”, invites high-quality submissions focused on real-world improvements in surgical techniques, patient selection, perioperative management, and long-term outcomes. We welcome the submission of original research articles, clinical trials, and systematic reviews (+/− meta-analyses) that explore surgical strategies in benign and malignant disease, innovations in minimally invasive approaches, risk stratification, and postoperative complication prevention.

Particular emphasis will be placed on evidence-based practices that improve patient safety and outcomes, including enhanced recovery protocols, surgical education, and the multidisciplinary management of surgical disease. Submissions that evaluate the role of technology (e.g., intraoperative imaging or AI-supported clinical decision-making) are also welcome to be submitted, provided that they are firmly grounded in clinical utility and outcomes.

This Special Issue seeks to bring together the expertise of abdominal surgeons and multidisciplinary teams to advance the field through critical evaluation and the dissemination of clinically relevant innovations.

Background: Surgical procedures and alterations of the gastrointestinal (GI) tract increase the risk of small intestinal bacterial overgrowth (SIBO), which is associated with GI symptoms and complications that compromise postoperative recovery. However, the prevalence and clinical impact of SIBO after various upper GI surgical procedures remain poorly understood. Objective: This study aimed to evaluate the prevalence of SIBO after different types of upper GI surgery and to investigate the associated clinical factors. Methods: We conducted an observational study involving 157 patients with a history of upper GI surgery: Roux-en-Y gastric bypass (RYGB), laparoscopic single-anastomosis gastric bypass (OAGB), subtotal (STG) or total gastrectomy (TG), subtotal (SP)or total pancreatectomy (TP), cephalic duodenopancreatectomy (WR), and small bowel resection for Crohn’s disease. A glucose–hydrogen breath test was performed, and demographic, clinical, and treatment-related data were collected. Statistical analyses included t-tests, non-parametric tests, ANOVA, and correlation analyses using R software. Results: At a median follow-up of 25.7 ± 18.1 months, 31% (48/157) of patients tested positive for SIBO. The highest prevalence was observed after RYGB and OAGB (43%), followed by TG (30%), STG (29%), TP/WR (28%), and Crohn’s disease bowel resection (19%). No cases of SIBO were observed after SP. SIBO positivity was significantly associated with bloating and flatulence (p = 0.002), lactose intolerance (p = 0.047), systemic sclerosis (p = 0.042), T2D (p = 0.002), and exposure to adjuvant chemotherapy (p = 0.001) and radiotherapy (p = 0.027). In addition, the risk of SIBO increased proportionally with the duration of GI resection or exclusion (p = 0.013). Conclusions: In our study, the prevalence of SIBO after upper GI surgery was 31%, with the highest incidence (43%) observed in metabolic surgery patients. Importantly, adjuvant radio/chemotherapy was associated with an increased risk of SIBO, and extensive small bowel resection or exclusion was strongly associated with an increased risk of SIBO. Furthermore, the limitations of current diagnostic methods, which lack sufficient sensitivity and specificity, highlight the importance of early screening and standardization of diagnostic techniques to improve patient management and outcomes.
